摘要： An apparatus and method in a heterogeneous wireless communication system reconnect a Mobile Station (MS) to a previously connected cell upon occurrence of a Radio Link Failure (RLF) in a current cell when a portion of a coverage of the second cell is included in a coverage of the first cell. A Mobile Station (MS) stores system information of a first Base Station (BS) of a first cell when performing handover from the first cell to a second cell. When changed system information of the first BS is received from a second BS of the second cell, the MS updates the stored system information using the changed system information. When detecting that a connection with the second cell is lost prior to a handover from the second cell, the MS performs reconnection to the first BS using the stored system information.

摘要： A method and an apparatus are disclosed for applying frequency layer convergence (FLC) to connected mode user equipments (UE) having no dedicated channel for a multimedia broadcast/multicast service (MBMS) service in a mobile communication system employing a Code Division Multiple Access (CDMA) scheme. The method and apparatus prevent uplink signaling congestion which may occur when the UEs located in non preferred frequency layers (NPL) of the MBMS service move to a preferred frequency layers (PL) when a MBMS service session starts. If the MBMS service session starts in a situation of applying the FLC, a radio network controller (RNC) notifies the UEs desiring to receive the MBMS service and located in NPLs for the MBMS service of FLC information including a PF value and a timer value, with reference to the number of the NPL UEs joining the MBMS service. The UEs performs a PF test according to the PF and timer values, thereby maintaining the degree of congestion and signal transmission load at appropriate levels.

The discontinuous reception method includes: receiving DRX information for DRX operation based on DRX cycles having an on-duration and an off-duration; determining, when semi-persistent resources are allocated, an offset of the DRX cycles so that the time of semi-persistent resource allocation belongs to the on-duration of one DRX cycle; checking whether a packet is successfully received through the allocated semi-persistent resources; and performing, when a packet is successfully received, DRX operation according to the received DRX information and determined offset. The discontinuous reception apparatus performs discontinuous reception using the method.

摘要： A method for requesting packet retransmission in a wireless communication system is provided. The method includes checking, by a receiving-side Automatic Retransmission reQuest (ARQ) layer, sequence numbers of received packets to determine whether there is any missing packet, and starting a first timer in association with the missing packet; stopping the first timer upon receiving an Hybrid ARQ (HARQ) reception failure indicator corresponding to the missing packet, provided from a receiving-side HARQ layer; and stopping generation of a status report message corresponding to the missing packet, and waiting for an ARQ packet corresponding to the missing packet, retransmitted from a transmitting-side ARQ layer.

摘要： Disclosed is a method and an apparatus for periodically reporting the buffer status in a mobile communication system. If there is a possibility that a transmission resource will be allocated to the UE, it stands by for a predetermined period of time until a transmission resource is allocated instead of directly transmitting a buffer status report so that, if possible, the buffer status report message is piggy-backed onto uplink data and transmitted.

摘要： A method and apparatus for enabling efficient use of radio resources by reducing an RLC PDU size in a mobile communication system supporting voice service over a packet network are provided. An RLC layer constructs an RLC PDU without inserting information indicating the start and end of an SDU or indicating the use or non-use of padding. The RLC layer sets an LI in a header to indicate inclusion of an intermediate SDU segment in the data field of the RLC PDU. Therefore, the resulting decrease of overhead arising from packet transmission facilitates the efficient use of limited radio resources.
